Google has become an investor in Mathpresso, a startup behind an AI-based educational application. Mathpresso, the Seoul-based edtech company behind QANDA, an AI-based learning app for K-12 students, announced it has added Google as a new investor. Google's undisclosed investment is not part of its Series C, raised in June, the company said, without providing its valuation. The additional investment event comes five months after its $50 million Series C round, which brought its total funding to $105 million in June. The company's previous backers include SoftBank Venture Asia, MiraeAsset Venture Investment, Smilegate Investment, Samsung Venture Investment Corporation, and Legend Capital.

QANDA's AI-powered Optical Character Recognition (OCR) technology, added in 2017, recognizes text and mathematical formulas in a photo and allows users to search for answers in seconds.
